If I can't figure out #1 then #2 is my alternative. #1 I can't get my quadrajet I recently swapped on to idle. It will fluxuate from 900-1500 rpm's. I checked all over and it isn't a vacum leak, I believe it is something to do with the choke, or perhaps maybe even the timing. I am running a big cam so that isn't helping a whole lot. Also when I try to drive it while it is fluxuating there is no power, and I can't wind up the motor at all. #2 I am going to try and run a demon carb on my truck, problem is it only has 2 vacum ports. 1 for the advance and one for the brakes. I am wondering if I can put a T in the brake hose and connect the pcv valve that way or if it will depleet my vacum too much and affect my brakes. Thanks guys.
